Application March 2, 1934, Serial No. 713,676

15 Claims.

The main objects of this invention are:

First, to provide an apparatus for forming banded wrappers and delivering the same to a wrapping machine.

Second, to provide an apparatus whereby a strip of paper, which may carry suitable adver-.

tising or other desired matter, is applied and eifectively secured to a web of waxed wrapping paper.

acter which may readily be applied to machines now quite extensively used. v

Fourth, to provide a method of forming banded" wrappers which is highly practical and may be practiced with a minimum of expense.

Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, in which:

Fig. l is a fragmentary side elevation of a wrapping machine embodying the features of my invention, the wrapping machine being shown conventionally.

Fig. 2is a fragmentary plan view.

Fig. 3 is an enlarged detail view in section on line 33 of Figs. 2 and 4.

Fig. 4 is an enlarged fragmentary view of certain of the parts shown in Fig. 2 with the banding strip spool empty. 7

Fig. 5 is an enlarged fragmentary view partially in vertical section of a modified form or embodiment of my invention.

Fig. 6 is an enlarged fragmentary view partially in section of still another form or embodiment of my invention.

Fig. 7 is a fragmentary perspective View of one of the wrappers.

Fig. 8 is a perspective View of a loaf of bread with one of the wrappers applied thereto.

In the accompanying drawings I represents a wrapping machine. Qperatively associated with the wrapping machine is a pair of coacting feed rollers 2 and 3, the roller 3 being a pressure roll. These feedrollers deliver to a rotary cutter 4 and its coacting supporting roll 5. The machine is provided with a support 6 for a roll of wrapping paper 1. The web of paper 8 is .drawn from this roll by the feed rollers, the

spindle of the roll being indicated at 9.

The hanger i0 is pivotal'iy mounted at H on the bracket I! so that the hanger isv normally supported in an inclined position, the pivot be Third, to provide an apparatus of this charing in the form of a rod and the hanger being adjustable longitudinally of the rod so as to enable the positioning of the banding strip l3 as may be'desired on the web 8. The rod is provided with a support 4 with which the hanger may be engaged to support the parts in operative position.

The hanger has laterally projecting arms 15 and E6, the arm l6 being carried by the rod 11. These arms are'provided with bearings for the spindle! of the spool I9 for the ribbon-like banding strip l3. The strip i3 is passed from the spool around the rotatably mounted sealer element 20, the heating element thereof being indicated at 2| within the tubular shaft or spindle of the sealer element. This spindle is carried by the depending arm 22 on the hanger. The pivoted support for the hanger is disposed above the roll l and in such relation to its spindle 9 that the hanger is free to swing to and from the axis of the roll.

The hanger through the sealer member 20, which constitutes a guide, acts to press the strip of paper against the periphery of the roll so that it is supported for a substantial period by the roll, permitting setting of the wax before the web livered to the cutter and to the Wrapping machine, the details of the wrapping machine not being illustrated.

In the modification shown in Fig. 5 the hanger 23 carries a shoe-like sealer element 24 disposed in opposed relation to the yieldably supported plate 25, this plate and the sealer engaging the web and strip in opposed relation at'a point intermediate the feed rolls and the roll I. The hanger in this embodiment is provided with a guide roll 26 around which the strip I3 is led from the spool. This embodiment also allows for the swinging of the hanger transversely to the axis of the roll of wrapping paper.

In the embodiment of my invention shown in Fig. 6 the hanger2l carries the sealing roller 28 at its lower end and a pressure roller 29 disposed above the sealing roller and coacting there-. with to hold the strip l3 against the periphery of the roll of wrapping paper I. I

In all of these embodiments the feed means acts onboth the web and strip and the strip is superimposed upon and sealed longitudinally of Fig. '7.

In Fig. 8 a wrapper is shown applied to a loaf of bread the relation of the strip to the wrapper appearing in this figure.- It will be understood, however, that the strip may be positioned as desired on the wrapper, that is, centrally or toward either side, this result being obtained merely by the adjustment of the hanger on its pivot rod. In Fig. 8 I have indicated the strip as bearing printed matter but it will be understood that it may bear any matter desired or may be of a diiferent color from the wrapper. It not only serves to provide proper advertising, identifying or ornamenting means but also serves to reinforce the wrapper,

This method ofjoining the wrapper and the bands may be practiced as a continuous method. The apparatus is simple and may be attached to or embodied in machines now quite extensively used.

I have illustrated certain very practical embodiments of my invention but have not attempted to illustrate all of "the embodiments or adaptations which I contemplate as it is believed that this disclosure will enable those skilled in the art to embodyor adapt my improvements as may be desired.

' Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
